No let up for firefighters

Fire crews battling uncontrolled bushfires in Tasmania's south are not slowing down their efforts despite cooler weather conditions.

Mild temperatures are expected to rise and winds strengthen throughout the afternoon, with a top of 30 degrees forecast for the Upper Derwent Valley where crews are trying to contain a large blaze.

Crews are also fighting major fires at Steppes and between Forcett and the Tasman Peninsula.

Fire service spokesman John Holloway says back burning has been suspended as wind speeds pick up.

"Whilst those temperatures or winds won't be that strong we're still expecting them to affect these fires so people in both areas, or anywhere near the fires that are currently running, need to be quite careful, maintain their bushfire plan."
